30

coffees in all,

70\%

of which were regular. How many regular coffees did the cafe serve?

regular coffees

Identify Total Coffees: Step $1$ : Identify total coffees and percentage of regular coffees. $\newline$ Total coffees served = $30$ $\newline$ Percentage of regular coffees = $70\%$ $\newline$ Calculation: $(\text{Total coffees}) \times (\text{Percentage of regular coffees}) / 100$ $\newline$ $30 \times 70 / 100 = 21$
